.Tllis invention relates to improvements in vein retainers and, more especially, such a: device or instrument adapted foruse n 11 1-1 tra-venous therapy or surgery.

For example,'in drawing blood from a vein or injecting medicative fluids, or the like, into a vein, it is frequentlynecessary or desirable to fix or to hold the vein in place under the skin in order to permit the insention ofa hypodermic needle or otherlinstru ment.

provision of such a device that is simple in for a variety of applications.

Other features and advantages of my invention will appear more fully as I proceed with my specification.

In that form of device embodying the features of my invention shown in the accompanying drawings Figure l is a view in perspective, showing the instrument in use on a patients forearm; Fig. 2 is a similar view, on an enlarged scale, showing insertion of a hypodermic needle into the vein; Fig. 3 is a View taken as indicated by the line 3 of Fig. 2; Fig. 4 is a view taken as indicated by the line 4 of Fig. 3; and Fig. 5 is a View in perspective of the underside of the instrument.

As shown in the drawings, may indicate any part of the body, here shown, for example, as a patients forearm. Numeral 11 indicates one of the veins that is to be fixed, retained, or held in place under the skin in order to permit any work thereon, for example, the insertion thereinto of a hypodermic needle 12. s s

My improved device includes a substantially rectangular supporting-plate 13 with means for holding the same on a part of the body, said means here shown as including a flexible strap 14 adapted to be passed around the forearm 10 or other part of the body and secured at both ends to the plate 13 by means of suitable buckles or clamps l5, 15 of wellknown construction.

The supporting-plate 13 is provided at one side with a rather deep square recess or notch 16. On the under side of the plate, at

One of thefe'atures of my invention is the construction, easy to operate, and adapted each side of this notch 16, there is slidably mounted aflat retaining finger lZ having its forward edge bent downwardly, asindicat ed by 17, Theslides for the finger 17 are made in the following manner, Oneedgeof the plate 13is bent downwardly and inward- 1y, as indicated by 13*, and the opposite edge carries. a strip ISsecured thereto by the rivets19. The lnner edgesofthe strip 18 and the bent-back flange 13% are undercut, as in-' dicated by 20 'and 21, "respectively," The edges 'offthe retaining finger l'z'are 'corre spondinglybeveledso that these fingers 17f are adapted toslide toward or away from each other." p v In order to adjustthe sliding movement of the finger 1 7," and lace themin the desired positions, each of the fingers 17 is pro 1 vided .withan upwardly projecting post 22 having a threaded hole therethrough accommodating one end of a double threaded screw 23'adapted't o be rotated by the' knurled thumb nut 24. It will be seen that rotation of the nut/24 will draw the fingers 17 toward or away from each'other.

Theunderside of the plate 13 is al s'o provided with a transversely arranged downwardly extendingedge having a notch therein adapted to lie across. the vein bein [retained and; serve to restrict or shut 0 flow of blood therein and,]also,to assist in centering "the device over the vein. part is here shown as formed on the under? side of the strip 18,- as indicated by 251 Thenotch therein is'i'ndicated lby 25. It

will be seen that the center of the notch 25 is substantially in line with a. median line between the edges 17*, 175 f the fingers. In applying, the device, the edge 25 is prefera .y that ow of bloo'd'toward the heart 'will b e restricted by this edge 25, causing the vein tjos'well up or expand between theretaining fingers'17,,17.. j I

The extentito which;the finge S? are tightened and the degree to which they are forced into the flesh will dependiuponzlocal conditions. For example, in Fig. 3, there is lllustrated moreorless diagram matically, the position thatthefingers might take when-the vein. is being retained, or fixed, for: work: thereon. r I While I; have shown and described cer tainembodiments of'my-invent-i'o'n, it is to be. understood-- thatv it is" capable of many modifications." Ghanges, therefore, in the eonstructionandarrangement may be made without departing from -the spirit and scope ofJ-my invention as disclosed in the appcn'd 'ed claims, in which it is my intention to claimall novelty. inherent inmy invention as 'broa dly as possible, in;vie w of'theprior What I regard as new,and' desire to.se-
